Description

A shelf system for supermarkets

technical field

The utility model relates to the field of supermarket supplies, in particular to a shelf system for supermarkets. the

Background technique

In the supermarkets of large and medium-sized shopping malls, due to the large number of customers, especially during the Spring Festival and other holidays or shopping peaks, there are many customers who buy goods, and the goods on the shelves may not be replenished in time, and because a staff member in the shopping mall It is often necessary to be responsible for the supply of goods in an area, and the staff need to constantly patrol the shelves in the managed area to prevent insufficient supply of goods, which will increase the labor intensity of the staff, and during the peak shopping period, the staff are often too busy If you are busy, you can't find out that the supply of goods on the shelves is insufficient and replenish them in time, which causes great inconvenience to customers. If each shelf is equipped with a staff member who manages the shelves, the cost will increase significantly. the

Contents of the invention

In order to solve the above problems, the utility model provides a kind of situation that can sense the lack of goods on the shelf and give a timely alarm to the control center.

The integrated processing chip is LT174, and the transistor is a S9013 or C8050 or S8050 type NPN transistor.

The control center is provided with a signal transmitter, which transmits the signals of the indicator light and the buzzer to the signal receiver through GSM.

The utility model uses a time-delay capacitor C1 in the control circuit. When the customer presses the goods on the pallet and leaves at the moment of purchase, the +12V voltage will charge C1 through the first resistor R1, because the voltage at both ends of C1 cannot be mutated. , so that the transistor V will not be turned on immediately when the pressure of the pallet changes instantaneously, causing false alarms.

When the pressure value of the pallet is greater than the set value of the sensor, the signal is low level, so that the transistor is cut off, VL does not emit light, and the buzzer does not work; when the pressure value of the pallet is less than or equal to the set value of the sensor, the signal is High level, the transistor is turned on, and the high level output by its emitter will light up VL, and at the same time IC works, HA sends out an alarm sound.

The beneficial positive effect of the utility model is:

The utility model sets the pallet of the shelf as an elastic material, and arranges a sensor at the bottom of the pallet to sense the pressure on the pallet. When the goods on the pallet are insufficient, the pressure on the pallet is reduced so that the sensor transmits the signal To the controller, the controller passes through the processing circuit to make the indicator light and buzzer set in the control center work, prompting the personnel in the control center to replenish the information of the specific shelf, and send the signal to the shelf equipped with the signal receiver through the transmitter using GSM The staff can send a timely replenishment signal, or the control center can also prompt the shelf staff through broadcasting. The utility model can be used with multiple shelves at the same time. It is not only simple in structure, but also practical, convenient and low in cost. the
